# Best Inverse Function Calculator | FOX8 WGHP

## Which inverse function calculator is the best?

If you’re taking a math class where you study inverse functions, you’ll probably need to graph functions and their inverses in a number of ways. An inverse function graphing calculator will allow you to graph functions quickly and accurately, which will help you visualize the behavior of those graphs. This allows you to graph accurately by other methods.

Just like any number has an inverse, many functions also have inverses. For example, the reciprocal of 5 is ⅕. The inverse of the function y = x is y = 1/x. You can find the inverse of a function algebraically, but graphing it is a great way to visualize how an inverse function cancels its parent function. To produce high-quality function graphs, the Texas Instruments TI-Nspire CX II CAS Color Graphing Calculator is the first choice.

## What is an Inverse Graphing Calculator?

An inverse graphing calculator is a graphing calculator capable of graphing the inverse of a function. Suppose you are used to using basic mathematical or scientific calculators limited to operations such as addition and multiplication. In this case, you will be blown away by the collection of functions offered by an inverse graphing calculator.

Inverse graphing calculators help higher-level math students, such as those in advanced algebra and pre-calculus, visualize functions and their inverses to learn how graphs behave. They are powerful tools for learning in the palm of your hand.

## What to know before buying an inverse function calculator

### Processing speed

Faster processors will allow you to work faster. Manufacturers measure speed in megahertz.

### Course or test requirements

Be sure to pay close attention to the requirements listed on your syllabus or in the guidelines for any exam you plan to use your calculator for before purchasing one. Some classes and exams have specific requirements as to which calculator is allowed.

## What to Look for in a Quality Inverse Function Calculator

### Battery

Most inverse function graphing calculators run on rechargeable batteries, saving you money and eliminating the hassle of buying new batteries. To avoid the recurring expense of replacing your batteries, be sure to look for a model with a rechargeable battery. It’s crucial to research this feature if you’re considering older models, which often used disposable batteries.

### To display

The display of your graphing calculator will have an impact on the use of your calculator in class or at home for studying. Choosing an inverse function calculator with a high definition backlit display will make it easier to use your calculator for long hours or late at night without having to decipher the details.

Color screens are also useful for differentiating between different lines drawn on the same path.

### Memory

Choose an inverse function calculator with a good amount of memory to store the functions and equations you use most often. This is especially useful in higher-level math classes where you do a lot of advanced calculations.

## How much you can expect to spend on an inverse function calculator

Inverse function graphing calculators range in price from $60 to $300. Lower end calculators will meet all the basic requirements of an inverse function calculator, but will not have as high quality display as higher end calculators. For $150 to $300, expect color displays and high capacity with features like 3D modeling and statistical analysis.

## Inverse Function Calculator FAQ

### Which line should the inverse function reflect on my calculator?

**A. **When manually graphing an inverse function, first draw the origin function. Next, draw the line y = x on the same Cartesian plane. Represent it as a dotted line to help you visualize how each point on your graph is reflected on that line. Note that this line passes through the origin (0,0) of the graph and has a slope of 1.

### Do I need to be able to graph inverse functions by hand?

**A. **In almost every math class where inverse functions are taught, you will need to learn how to graph them by hand. However, it involves reasonably simple calculations that are easy to understand with a little practice. Having a graphing calculator that can quickly and accurately graph the inverse of a function will allow you to visualize how inverse functions work and act as an essential supplemental tool as you master graphing functions and their inverses by various methods.

### How can I solve an inverse function in two ways?

**A. **The first way to solve an inverse function is to graph it by hand or on your graphing calculator. To plot a graph by hand, plot the origin function, then reflect its coordinates on the y=x line. The second way to graph the inverse function is algebraically. Start with the original equation function, swap x and y, then solve. For example:

f(x) = 5x +10 (original function of x)

y = 5x + 10 (change function notation to y)

x = 5y +10 (to find the inverse function, swap x and y)

(x – 10)/5 = y (solve the equation for y)

f-1(x) = x – 105 (arrange in normal function notation)
